Reputation has often been proposed as the central mechanism that creates trust in the sharing economy. However, some sharing platforms that focus primarily on social rather than economically driven exchanges have managed to facilitate exchanges between users without the use of a reputation system. This could indicate that socially driven exchanges are in less need of reputation systems and that having sufficient trust is less problematic. We examine the effect of seller reputation on sales and price as proxies for trust, using a large dataset from a Dutch meal-sharing platform. This platform aims to stimulate social interactions between people via meal sharing. Multilevel regression analyses were used to test the association of reputation with trust. Our main empirical results are that reputation affects both sales and price positively, consistent with the existing reputation literature. We also found evidence of the presence of an information effect, i.e., the influence of reputation on sharing decreases when additional profile information is provided (e.g., a profile photo, a product description). Our results thus confirm the effectiveness of reputation in more socially driven exchanges also. Consequently, platform owners are advised to use reputation on their platform to increase sharing between its users.

This paper describes the development and results of the pedagogical photo-based method PhotoReflexivity. This method is designed to support reflexivity for students in design education, which guides them in better understanding and situating themselves in the outside world. To uncover the value of this method, mixed research methods including iterative prototypes were deployed in real-world learning scenarios with design students. Attitudes, behaviour, and reflexive conversations were analysed, from which design patterns and recommendations were derived. It is argued that PhotoReflexivity fills a gap in design education by aiming for extensive and transformational outcomes associated with reflexivity, which previous research has considered hard to achieve. It does so by providing pragmatic technologies and materials to support 1) sharing and collaboration, and 2) verbalising reflexive thoughts. By facilitating reflexivity, students might become more autonomous and responsible design professionals.
Differences between tourists in photographing and photo-sharing behaviours have been under-researched. We examined the influence of geographic origin and travel group composition on tourist photographing and sharing. Questionnaires were used to measure photographing and sharing frequency, while participant observation afforded a deeper examination of sharing processes. Findings showed differences in photography behaviour between solo and accompanied tourists. Tourists from some continents also took and shared photographs more frequently. Observations uncovered processes connecting sharing, photographing, and content of photographs. As user-generated content becomes increasingly influential in tourism management, attention to origin, group composition and other individual differences can help engage tourists in photographing and sharing.
